g. If ammeter reading is greater than 0.2 amp, AVR is faulty. Replace AVR. If not, continue.
h. Measure voltage across AVR terminals X and XX. Voltage should be 1 volt DC or greater.
i. Slowly turn the variable autotransformer up to 100 volts. The 100 W lamp should glow.
j. Slowly turn the variable autotransformer up to 200 volts. The 100 W lamp should go out.
k. Slowly turn the variable autotransformer down to 100 volts. The 100 W lamp should glow.
l. Reinstall AVR (steps e through h of "REPLACE").
